pubmed-article:21595441 | pubmed:abstractText | The utility of 193-nm ultraviolet photodissociation (UVPD) and 10.6-?m infrared multiphoton dissociation (IRMPD) for the characterization of lipid A structures was assessed in an ion trap mass spectrometer. The fragmentation behavior of lipid A species was also evaluated by activated-electron photodetachment (a-EPD), which uses 193-nm photons to create charge reduced radicals that are subsequently dissociated by collisional activation. In contrast to collision-induced dissociation (CID), IRMPD offered the ability to selectively differentiate product ions with varying degrees of phosphorylation because of the increased photoabsorption cross sections and thus dissociation of phosphate-containing species. Both 193-nm UVPD and a-EPD yielded higher abundances and a larger array of product ions arising from C-C cleavages, as well as cross-ring and inter-ring glucosamine cleavages, compared to CID and IRMPD, because of high energy, single-photon absorption, and/or radical-directed dissociation. UVPD at 193 nm also exhibited enhanced cleavage between the amine and carbonyl groups on the 2- and 2'-linked primary acyl chains. Lastly, UVPD of phosphorylethanolamine-modified lipid A species resulted in preferential cleavage of the C-O bond between ethanolamine and phosphate, enabling the selective identification of this modification. | lld:pubmed |
